' This invention relates to bobbin holders of the typsemployed in holding bobbins, in position for winding or unwindingin textile machinery such for example as `spinning machines and winding "With certain constructionsof bobbin holders the bobbinis heldin place by simple friction, and such reliance upon simple friction may give rise `ious''constructions employing clamps or catches ortheilik'e as a substitute for simple friction have been devised, butin general such expedients are likelyto introduce other diicultiespsuch as interference with easeof application orremoval of 'i'.hebobbin,` complication of construction, 4or likelihood of breakage.

The inventionr aims to provide a bobbin holder with which it is easy to place the bobbin in seated `position on the holder and easy to remove the bobbin from the holder, but which will securely hold the` bobbin against accidental displacement,

and to accomplishthisby means of a simple durable construction.

fOtherl objects `of the invention and advantagecusfeatureslwill be apparent from this speciiication and itsdrawings wherein the invention 'isvexplained bya description of a preferred embodiment of abobbin holder for awindin'g machine and of a` preferredembodiment of a bobbin hplder Ifor a spinning or similar machine. The il- Instr-ated Awinding machine bobbinY holder is adaptedfor frictional drive of the winding pack- `age by meansof a drive roll but is equipped with `a tire of resilient material for relieving the bobbin fromV contact with such drive roll until the rst few layers of yarn have been wound, the tire serv- 11 Claims.

The illustrated spinning `machine'bcbbin` holder is of thedrivenvspindle type.

In the drawings, l Fig. 1 is a horizontal sectional view showing a preferred form of bobbin holder for a winding machine, the bobbin being in place thereon; f

Fig.` 5 'is a vertical sectional view showing a preferred form of bobbin holderA for, a spinning or similar machine, the bobbin being in place thereon and the upper portion of the view being taken on the line 5-5 of Fig. 6; and f Fig. 6 is a top end elevation of the bobbin holder of Fig. 5, omitting the bobbin.

The" bobbin holder of Figs. 1 to 4, for use in winding machines, .is especially adapted for holding bobbins which are formed as perforated stainless'steel tubes-I Ilfor use in dyeing yarn, as for P instance inthe dyeing apparatus of UnitedStates patent application Serial No. 87,873, filed April 16, 1949, noWPatent No. 2,577,727 dated December 11, 1951. A woundpackage'P of yarn to be dyed 'is wound jupon the bobbin I Iwhile the package rests upon andfis driven by a rotating drive roll I2'as shown inFig.'4."

The bobbin holder includes the usual interior end andpenetrating 'a tubular'arm I1 which may F be a part fof `the usual pvotally mounted spindlecarrying arm tha-t positions the spindle and winding package for movement away from the drive roll as the winding vpackage" grows.

` A sleeve I8 carrying bushings I9 and 20 is rotatably mounted on the spindle I5 and carries the elements for supporting the bobbin. An end Washer 2 I, shown in Fig. 1 and removed in Fig. 2, may be employed to lretain the sleeve and its as'- sociated parts upon the spindle I5. l

A base-centering element 22 over which the 'base o'f the bcbbinzll is adapted to be snpped has a peripheral conical surface v22a"of slightly greaterV taper than that of the interior of the bobbin I I so as to facilitate placing the bobbin vthereon and accurately centering the bobbin. The basecentering element4 22 preferably carries a tire 25 of resilient material such as rubber having a slightly larger diameter than the largest diameter of the conical bobbin I I so asto4 relieve the metal surface of the bobbin from contact with the friction drive roll, as shown in Fig. 3, during the winding of the rst few layers of yarn, on the bobbin,

thus avoiding cutting the yarn between the bobbin and drive roll in the device as shown, or cutting the drive roll in case a grooved drive roll of plastic material is used. During the winding of these Afirst few' layers the tire' 25 contacts wi-th theroll I2 and thus drives the bobbin holder and bobbin,

following which the'tire 25 leaves contact'with the roll I2 `'and the package is driven by contact ofits yarn with the roll I2, as for instance in the later stage shown in Fig. 4.

The base end of the conical bobbin preferably abuts against the side face of the resilient tire 25, and in this position the base endoportion of the bobbin is engaged frictionally by the basecentering element on only a narrow part ofthe periphery 22a of the base-centering element, so

that little friction is created between the bobbin holder is provided with a plurality of rollers 38 4 A spindle 49 having a reduced diameter blade portion 46a is mounted in a suitable conventional bearing in a base 42. A whirl 43 is secured to the spindle and has extending upwardly therefrom an integral extension 44 of smaller diameter adapted to enter inthe base portion of the bobbin. A conically tapered'portion Y45 of the whirl engages the base end of the bobbin 39 and acts as a base-centering element. A metal tip portion 48 is secured to the blade Mia in the region of the tip of the bobbin, and the space between the tip portion 48 and the extension 44 of the whirl is 'lled by a tube E0 which may be of spaced circumferentially'of the bobbin holder. n

With the bobbin in its seated position as.k shown 1in Fig. 2,' the three rollers together extend to diameter of a circle which is slightly larger `f than the smallest internal diameter of the bobbin: Thus during at least 'the last part of the operation of ,seating the `bobbin on the holder the one or more distortablerollers (preferably all of the rollers are distortable) is or are compressed slightly.

When the bobbin is seated, the position of the rollers with relation to the bobbin is such that an outwardly facing edge of the interior surface ofthe bobbin is engaged by the rollers,'with the centers of these` rollers lying outwardly, endwise of the bobbin holder, beyond suchedge. Inseating thel bobbin on the holder a. toggle action is secured as such outwardly facing edge passes the `centers of the several rollers, and the rollers thereupon retain the bobbin securely on the holder andpreclude accidental displacement of the. bobbin.

; The reverse toggle action occurs when the bobbin is removed and the one ormore resiliently .distortable rollers are distorted as the outwardly 'Y facing edge .of theinterior surface of .the bobbin is `moved endwise to the center lines of the rollers.

,'.The Yinvention combines the advantages of such vtoggle locking or unlocking action with the advantage of reduction of frictional drag as the bobbin is passedv over the rollers in seating `or 1 removing the bobbin.

It is preferred that all of the rollers be resiliently distortable, in order to reduce the necessary amount of distortion of any oneroller, to more securely hold the bobbin, and lalso to more accuratelycenter the tip end of the bobbin particularly in view of slight variations in diameter .f

of the tip ends as between individual bobbins.

'The bobbin holder of Figs. 5 and 6, for use in spinning and twisting machines is especially adapted for holding slightly tapered tubular bobbins 39 formed of paper or fiber composition.

wood or -b'er composition surrounding the blade.

The tipportion 48, tube 5D, and extension 44 correspond intaper to the slight taper of the bobbin 39and are slightly smaller in diameter than the inside of the bobbin so as to be slightly spaced therefrom when the bobbin vis seated on the base-centering element 45.

The tip Aportion 48 is recessed to receive three rollers 3i?, corresponding to the rollers 30 of Figs. o l to 4, each rotatable upon a shaft 32 which is secured withinfthe tip portion 48.

As in the device of Figs. l to 4 the bobbin may readily vbe slipped on over the rollers 30 which ywill rotate as they are contacted bythe interior of the bobbin. The three rollers 30 together extend to a diameter which is slightly larger than the smal-lest internal diameter of the bobbin, and the rollers are compressed slightly in the course of seating the bobbin on the holder.

Likewise, as in the case of the device of Figs. vl to 4, therollers 30 vin Figs. 5 and 6 are-so positioned with relation Yto the bobbin that an outwardly facing edge of the interior `surface of the bobbin is engaged by the rollerswith thecenters of these rollers lyingoutwardly, endwisejof the bobbin holder, beyond such edgeand when so engaged bythe rollers theV bobbin is securely held in seated position and prevented from .accidental displacement. y I j v In both the device of Figs. 1 tor 4 and the device of Figs. 5 and 6 the material of the bobbin has been shown as being uniform in thickness, the smallest internal diameter of the bobbin being at the tip end, and the outwardly facing edge of the interior surface of the bobbin,A engaged by the rollers 30 as described, is at the extreme end of the bobbin. However if there were an enlargement of the bore of the bobbin adjacent to the tip end,'such` outwardly facing edgeof the interior of the bobbin could be the edge of thel smallest diameter portion of the bore, and `could engage the rollers 30 at the locationof engagement'of the bobbin and rollers in eitherFig. 1 or Fig. 5, and a portion of thev bobbin-could extend outwardly beyond the rollers, that is to the left in Fig. l or upwardlyrin Fig. 5, preferably out of contact with-the rollers. Therefore it will be understood *thatk the outwardly facing edge of the interior of the bobbin, engaged as described with the rollers 39, is not necessarily at the extreme end of the bobbin, although so shown in the drawings in order to provide a bobbin of simplest construction.

With both illustrated forms ofthe invention the bobbin is easy to place on the bobbin holder and easy to' remove therefrom, but is securely held `against unintentional displacement. The bobbin l l` or 39 slips easily over `the rollers until just before the final seating ofthe-bobbin,*at which time the rollers, undergoinglcompression. briey oder a resistance tending to ,check `the endwise movement of the bobbimand finally as lstructureneed be employed.

thebbbm is seated, theiouers securely lock it `in-place. removing the bobbin asubstantial force must be exertedfor an instant, to `start "the 'outwardly facing edge ofthe interior surface of the bobbin outwardlyto the center lines of the "roller`s,'where`upon the bobbin comes off the hold#- engage with the cylindrical interior of the bobbin throughout passage of the whole length of the bobbin over the rollers, and then can assume the same locking relation to the seated bobbin as in the case of the illustrated conical bobbins.
